Even though it implements # CONFIG_RELOCATABLE, it does not implement CONFIG_RANDOMIZE_BASE and so # KASLR kernels (which are the main target of the feature) do not exist on # powerpc anyway. # # Reported-by: Andreas Schwab <schwab@linux-m68k.org> # Suggested-by: Nicholas Piggin <nicholas.piggin@gmail.com> # Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < git log --format=%s --max-count=1 ff69279a44e9ba876466b7d3ab84d6dbd31cac92 # < make -s -j 8 ARCH=sh O=/kisskb/build/linus_landisk_defconfig_sh4 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- landisk_defconfig # make -s -j 8 ARCH=sh O=/kisskb/build/linus_landisk_defconfig_sh4 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h <stdin>:1317:2: warning: #warning syscall pkey_mprotect not implemented [-Wcpp] <stdin>:1320:2: warning: #warning syscall pkey_alloc not implemented [-Wcpp] <stdin>:1323:2: warning: #warning syscall pkey_free not implemented [-Wcpp] <stdin>:1326:2: warning: #warning syscall statx not implemented [-Wcpp] <stdin>:1332:2: warning: #warning syscall io_pgetevents not implemented [-Wcpp] <stdin>:1335:2: warning: #warning syscall rseq not implemented [-Wcpp] /kisskb/src/arch/sh/kernel/cpu/sh4/../sh3/../../entry-common.S: Assembler messages: /kisskb/src/arch/sh/kernel/cpu/sh4/../sh3/../../entry-common.S:389: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh4/../sh3/../../entry-common.S:392: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:186:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:341:21: note: 'pdeo' was declared here /kisskb/src/drivers/net/tun.c: In function 'tun_get_user': /kisskb/src/drivers/net/tun.c:1836:30: warning: 'copylen' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/net/tun.c:1546:34: warning: 'linear' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/net/tun.c:1746:46: note: 'linear' was declared here /kisskb/src/drivers/sh/clk/cpg.c: In function 'r8': /kisskb/src/drivers/sh/clk/cpg.c:41:2: warning: passing argument 1 of 'ioread8' discards 'const' qualifier from pointer target type [enabled by default] /kisskb/src/include/asm-generic/iomap.h:29:21: note: expected 'void ' but argument is of type 'const void ' /kisskb/src/drivers/sh/clk/cpg.c: In function 'r16': /kisskb/src/drivers/sh/clk/cpg.c:46:2: warning: passing argument 1 of 'ioread16' discards 'const' qualifier from pointer target type [enabled by default] /kisskb/src/include/asm-generic/iomap.h:30:21: note: expected 'void ' but argument is of type 'const void ' /kisskb/src/drivers/sh/clk/cpg.c: In function 'r32': /kisskb/src/drivers/sh/clk/cpg.c:51:2: warning: passing argument 1 of 'ioread32' discards 'const' qualifier from pointer target type [enabled by default] /kisskb/src/include/asm-generic/iomap.h:32:21: note: expected 'void ' but argument is of type 'const void ' Kernel: arch/sh/boot/zImage is ready Completed OK # rm -rf /kisskb/build/linus_landisk_defconfig_sh4 # Build took: 0:01:14.055710
